BED-BOTTOM.

Specification of Letters Patent.

Patented Oct. 22 1907.

Application filed June 21,1907. Serial 1%. 380,073.

To all whom it may concern:

Be it known that 1, JOHN O. WEsNnn, a citizen of the United States,residing at Cameron, in the county of Orangeburg and State of SouthCarolina, have invented 5 certain new and useful Improvements inBed-Bottoms; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to bed bottoms provided with springs; and itconsists of a novel locking-wire for preventing the springs from beingdisplaced.

I n the drawings, Figure 1 is a plan view of a portion of a bed bottomconstructed according to this invention. Fig. 2 is a detail side view ofone of the locking wires.

Fig. 3 is an end view of the locking wire.

A is a portion of a wire frame of any approved construction whichextends around the springs.

B and B are portions of two adjacent springs, which are of any approvedhelical form. The top coil or convolution only is shown, for clearness.

G is a key wire which extends crosswise of the springs and which has itsends secured to the wire frame A in any approved manner.

D is the novel locking wire. This locking wire extends crosswise of thekey wire and its ends are secured to the wire frame in a similar manner.The locking wire is used in connection with the key wire to lock the topcoils of two adjacent springs, and also to lock the coil of each outerspring to the wire frame which comes adjacent to it. The locking wire 1)has a loop provided with side portions d which are arranged at an angleto the main portion of the locking wire. This loop has concave-convexhumps e in its main portion where the said main portion joins onto theloop, and these humps engage with the top coil of one of the springs B.The middle portion of the said loop is bent around to form a hook fwhich engages with the wire of the frame or with the wire of the nextadjacent spring. 'The extreme 40 point of the hook is bent over the wirewith which the said hook engages sufliciently far to form a channel 9for engaging with the key wire 0. The key wire is preferably arrangedunder the top coils of the springs, and the locking wire is preferablyarranged with its main portion nearly at a tangent to the top coils ofone row oi springs and so that its concave-convex humps hook over thetop coils of the said springs. The side portions (1 of the loops of thelocking wire are arranged below the top coils of the springs, and thehooks of the said loops are bent over the top sides of the said coils orover the top of the wire which forms the frame. The side portions 0! ofthe loops are angle-shaped so that they have knees d below the level ofthe point of the hook f and so that a space h is formed between thepoint of the hook and the side portions d, as shown in Fig. 3.

The locking-wires D are formed by machinery with the humps, hooks andloops complete, and the knees d enable the top coils of the springs, andthe frame A, to be slipped into engagement with the said hooks f, sothat the locking-wire does not have to be bent by hand when the partsare assembled in a bed-bottom. When the locking wires are constructed inthis manner and applied to the springs and frame as set forth, thesprings are retained in position in a more advantageous manner thanheretofore, as they cannot be displaced in any direction.

What I claim is:

The combination, with the coil of a spring, and a wire arranged adjacentthereto; of a key wire which extends crosswise of the said parts, and alocking wire which ongages with the said coil and which is provided witha laterally projecting loop having angle-shaped side portions the apicesof which project downwardly below the plane of the top of the bedbottom, said loop terminating in a hook which engages with the said wireand key wire, and a space being formed between the point of the saidhook and the side portions of the said loop so that the hook does notrequire to be bent after the said parts are assembled.

In testimony whereof I have atfixed my signature in the presence of twowitnesses.
